The result will always be a negative value. The difference can be looked upon in a neutral way, or depending on the calculation, you may want to say there is a difference by a particular sign. We would normally look on the difference in a positive way. -7 - 5 is - 12. The difference between -7 and -12 is 5. However if you are going from -7 to -12 you have a -5 difference, while going from -12 to -7 you have a 5 difference. So it can depend on perspective.
